In summary, there were 7 more cancer cases confirmed since the last report on November 12, 2013. One case was confirmed in a female from Namie Town, 5 in Koriyama City, and 1 in Izumizaki Village.

The total number of cases confirmed or suspected of cancer is 75. Of these, 34 had surgeries as of December 31, 2013, and 1 turned out to be a benign nodule, 32 were confirmed to be papillary thyroid cancer, and 1 still has no confirmed cytological diagnosis but listed as poorly differentiated thyroid cancer. (The total number of cases confirmed or suspected of cancer is often reported as 74 in news report, excluding the case confirmed to be benign).

Shinichi Suzuki, a Fukushima Medical University physician in charge of the thyroid ultrasound examination, cautioned against jumping to the conclusion about this "poorly differentiated cancer" which normally is associated with a poor prognosis. Although he did not elaborate on details, he said the diagnostic criteria for poorly differentiated thyroid cancer have recently changed. This was the case which, initially thought of as papillary thyroid cancer, was undergoing cytological reevaluation by pathologists who are still not sure about the exact subtype.

Interestingly, the first thing Suzuki mentioned, when it was his turn to present the thyroid examination results at the committee meeting, was the news post published today in multiple newspapers regarding the Fukushima Medical University beginning a genetic analysis of the cancer tissues. The news post states that Fukushima Medical University will use the thyroid cancer tissues, excised during surgeries, to analyze for genetic alterations to help figure out why the cancer originated. What was odd was that Suzuki, as if avoiding a swarm of questions, offered an explanation that such genetic analyses are routinely performed on adult cancer specimen using the special research money and approved by the University's ethics committee. He emphasized that the genetic analysis was totally separate from the thyroid ultrasound examination. He asked for an understanding as he felt it was the mission of Fukushima Medical University to conduct the genetic analysis in order to watch over the children's future.

As for the perceived "slow" speed of confirming the cancer cases, Suzuki said that some of the cases suspected of cancer did not warrant immediate surgeries, allowing for the children to live their lives with close monitoring.

As usual, no information was offered such as the type of nodules and also details of each surgical case which, as part of regular medical care, are considered beyond the scope of the screening and thus inaccessible to the Health Management Survey team.

This shows “incidence,” representing the rate of occurrence of new cases in a given period. On the other hand, Fukushima thyroid examination is mass screening, which yields “prevalence,” the proportion of the total number of cases to the total population.

It is important to note that incidence and prevalence are not directly comparable, so the incidence rates shown above are only a relative measure of comparison.

On March 8th, 2014, comedienne/journalist Mako Oshidori gave a lecture, "The Hidden Truth About Fukushima" in Düsseldorf, Germany, organized by a citizen's group, SAYONARA Genpatsu Düsseldorf. Translation of Mako Oshidori's March 6th, 2014 press conference at the German IPPNW (International Physicians for the Prevention of Nuclear War) Symposium in Frankfurt can be found here. The lecture, given in Japanese with German interpretation, was transcribed and translated into English.

Moderator: Good evening everyone. My name is Mariko. Welcome to a lecture by Mako Oshidori. As we all know, the Japanese people experienced the Great East Japan earthquake and tsunami on March 11, 2011. A huge earthquake, followed by tsunami and the nuclear accident, has become an unprecedented disaster for the Japanese as well as the rest of the world. Moreover, this accident is not only out of control but continues to be in critical state.As you may be aware, the issue of anti-nuclear power p…

On October 23-25, 2017, the Expert Group on Thyroid Monitoring after Nuclear Accidents (TM-NUC) met in Lyon, France for the first of two planned sessions (see this PDF for the agenda). The TM-NUC project was established by the International Agency for Research on Cancer (IARC) in order to "develop strategies and recommendations on how to plan and implement thyroid monitoring in populations possibly affected by radiation exposure due to nuclear accidents."

The aims of the TM-NUC project are to: assess the latest scientific evidence on the epidemiology, natural history, and clinical management of thyroid cancer, to develop principles for thyroid ultrasound examinations after nuclear accidents. This includes reviewing the scientific literature and compiling knowledge and experience from relevant countries.identify unmet research needs and propose epidemiological study designs to address these gaps in knowledge.According to the TM-NUC website, The Expert Group consists of 16 int…
